Frequently asked questions
What is the difference between pink and brown noise?
Pink noise drops by 3 dB per octave and sounds like steady rain. Brown noise drops faster and sounds like a deep rumble or a distant waterfall. Both are softer on the ears than white noise.
Are these recordings? Is there a copyright?
No. Every sound is generated live in your browser from filtered noise, so there are no recordings, no loops and no license restrictions.
Can I use it on my phone at night?
Yes. Keep the page open; on most phones playback continues with the screen off. Use a low volume for long listening.
